    Hi and Welcome to the Arbalist. Smile

    That's as simple as it gets and is a version of the trigger present in all pistol bows on the market.

    [PDF - Download Link]

    Has a little safety there too. Smile



    Basically it just pushes the string over the edge that retains the string.









    There are some patents for more complicated systems, but as far as I know, they didn't last long due to their complexity and thus impracticality for what is considered a leisure crossbow.







    ...Of course you can go for something like this, which is right there in the middle and can be safely called - *Best of both Worlds*. Smile


    Good Luck. Any questions welcome.

    Ivo

    Thanks Ivo,

    I cannot click the link to the PDF file for the top section.

    Please Elaborate......Basically it just pushes the string over the edge that retains the string. Orange and green diagram..Rolling Eyes

    That sounds like there are 2 strings in this design.?

    Have faith my friend - there is only *one* string.Laughing (and it's marked with a red dot)

    ...orange is the bolt that the string engages as soon as it's pushed over the edge by the green trigger piece.

    Thanks for the laugh - don't take this trigger design thing too seriously. When you don't understand something, try mocking it up. Print the design, cut out the parts, and pin them to a board (placing pins where the axels are) and see how the bits interact.

    Don't underestimate this paper mockup step, we all do it and not only to understand, but to also fine tune even more complicated designs. Great stuff this CAD(Cardboard Aided Design) thing. Smile

    Good Luck.

    Ivo

    PS: PDF Link Fixed. It's a patent...and not the only one out there by the way. Wink

    I like your idea of using a square pipe for the nut.

    Ivo wrote:



    This might look like it's not much, but it's quite sufficient (I never went past 175lb during testing though) and the lightest latch that I know of....here's the material/layout.




    And for a Pistol bow, a bull-pup trigger would be cool. That way you can bring the nut all the way back to the rear of the pistol for longer draw (faster bolts) and push the grip a little forward for better balance. Smile



    Pistol bows are sweet...My faves here... Cool Cool Cool







    Lol, and this sick puppy from the Gearhead boys!!!




    What'ya know...looks liek they all use a pull-pup style trigger.

    Yeh, that nut is pretty cool, not my idea though...just matching the design to widely available material - those sq. pipes can be found in any Homedepo/Lowes store and even in smaller hardware shops that have steel/aluminum stock bin somewhere in the corner.

    Antho

    There is a problem though...this nuts needs to be spring loaded( so that it resets automatically) and have a stop (so it doesn't spin through and wreck the springs)...AboMickey used a version of this group, but forgot the stop with all the resulting outcomes of inertia taking over upon release. >>> http://thearbalistguild.forumotion.com/t476-my-first-guild-crossbow-post

    Hope this helps. Smile And good to see you on the forum bro ...how long has it been since we saw each other in person? Razz You got any new projects started?
